Well, actually it does increase normally (compared to a similar karmic 
system which doesn't yield such lags):

           CPU0       CPU1       CPU2       CPU3
   0:         72        133    5761577      13517   IO-APIC-edge      timer

Well, I just might give it a try and see whether it does anything. On 
the other side I noticed there are some messages at dmesg regarding ACPI:

[    0.720325] ACPI: WMI: Mapper loaded

Is this something I should be worried of?
